A plication filed Decanter 5; 1528; steameates;

This invention relates to a loom for Weaving. I In the standard loomwhich is inalinost" universal use today, there is a warp beam whichprovides; the Warp threads'which are carried by the heddles andalternately raised and lowered to provide the required sheds into whichthe'weftthread's are woven.

The weft threads are provided by means of shuttles containing bobbinswound with weftthre'ad and which are passed to and fro through thesuceessive'warp sheds by means of picker-sticks which are operated bycam mechanisms. I

' These bobbins are each wound with a diferent coloredweft and theshuttleboxes usually n' ove vertically in' order to bring the propershuttle to a position inline with the shed of the warp. I

The bobbins which are carriedby the shut ties contain but a" very: smallamo untoi' thread and the shuttles are very carefully packed with feltor other soft material which exerts'a retardingaction' on the thread ofthe bobbin and preventsit fromfeeding there from in any greaterquantitythan desired.

7 These bobbins, on account of the small amount of thread" which theycarry; are' re quired to be changed quite f'requentlyso that there isgreat likelihood otdefects' 1n the cloth atthe ends of'theseweftthreadsywhilethe greatestloss arises froin'the necessity of Variousdeviceshave been recommended tor eliminating the necessity ofstoppingthe loom and thereforeyincreasing theoutput; and among which will befound my-copendingapplic ations, Serial No. 224,342, filed Denaazryeigezs; I I I I ceniber 1:927, and Serial No. 250,790; tiled shuttles andshuttle boxe's ha've' benf en lrely I eliminated and the weft threadsare selected and passed through the warp sheds 'by' rec1p-,

The

27 hand rail 28, reeds 29, heddle frames 30,

With the single exception of the lay, these ary manner and operateprecisely the same as they do in the conventional loom.

The left hand end of the lay, as shown in Figure 1, is extended, as at36, and the right like view with the thread and.

100111 has a frame'2l, arches22, dobby. 23, pattern cylinder 24c,'breastbeam 26, lay

' and left hand ends of the lay are provided But the warp may contain asmany colors as desired. and patterns may be woven into the fabric F bymeans of the pattern chain 40 which controls the operation of the acks45.

In the case of a plain or striped fabric, the dobby, pattern cylinder,and pattern chain may be omitted and two heddle'frames 30 may beoperated by a cam or other mechanism for forming the successive warpsheds.

The shuttle receivers 38 and 39 are provided, respectively, with pickersticks 11 and 42 which areoperated by cam mechanism, as in theconventional loom. On the right hand side of the loom is a platform' 43on which is mounted a cone box 441Wl113l1 is adapted to contain a coneof weft thread, the feed-0E strand of which is indicated by the letterX.

By reference to Figures 2, 3 and 4, it will be apparent that theweftthread X passes through a guide 16 mounted on the 100m frame. andthencepasses to a horizontal guide 47 illustrated in Figures 2, 3 and 4, andmounted on the front edge of the frame.

' From the guide 47, the weft thread makes a the inner edge of the upperend of the breast" beam and fromthence passes through the needle 53 andthen to thefab'ric, as shown .in

Figures 6, 7 and'8. The needle 53 is formed of a piece of tube and has acut-out portion .54 for receiving the thread. This needleis fastened tothe inner edge of the breast beam 26, as shown at .56 in Figure 2.

.fThe main shaft 57 of the its right hand end with a cam' 58.. This cam.

100111 is set in V motion bythe operation ofthe shipperhandle has a dualpurposeand one is to operate the clamp discs 49 and i 51 which shown inFigures 3 and 4. i

I An ogee "crank. 59 is pivotallyfastened to theframe-21 at the point'61and the upper are clearly 1:20, 7

arm 62 of this crank engages the 58, while 7 the lower arm 63 hassecuredthereto, by'any and in. linewith the breastbeaih 26, and is v. suitablemeans, a wire 64 which passes over a V then connected to'th'e shaftonone end at which the clamp" disc 49 is mtuntd;

By reference to Figure '9', it will be seen that the clamp disc 51' issecurely mounted in a pedestal 69fby the set screw 71', while the clutchdisc 49 is mounted 'onthe shaft 68" which is slidable in the bearingpedestal 72 and between this pedestal and the clamp disc 49 and 's'iir'roundingthe shaft, is a" spiral spring 73'; v r

The weft thread X rwhich is being fed from the'cone 130K544, will alwayspass" between the discs 49-an'd 51- and when there is no tension on thewire 64 so as to compress the spring? 3, the said spring will press thedisc 49 firmly against the di'sc 51 and therefore cla'mp-theweftthread'between said discs.

Let u's'con'si'der that a shuttle,rsuchas that shown in F ig ures ll,12'and 1'3, is being used for weaving-1 the weft thread into? the warp.Consider that the-shuttle is in the right hand shuttlerece'iver 38. Theca1n5 8 engages a follower 74 which is pivotally mounted on the frame21'; at 7 6. The outerend'of this follower is connected by a spiralspring 77 to the floor so that thefollower Will at all times bear on theearn 58 intermediate the pivotal point 7 6 1 and the outer end"connected with thespring77; The inner end of the follower ispivotallyconnected at 78 to a-rod' 79 which extends upward through a bearing 81,fastened to theinner side of the lay 27.

Secured'to'the upper end of the 'rod 79, by

suitablelocking nuts, is a plate 82 which eX- tend's'forward an'd'overthe lay 27, and is provided on its inner end with an actuating pin83fwlf1ich isslidaiblje'in said'pl'at'e by reason of the position of thelo ck nu'ts'84f and the flange nut86. 1

The: actuating" pin 83fjis' steadied in its operation by means, ofthe,annular bearing plate 85' through the horizontal portion of: whichjthesaid pin; passes and the" vertical part off fwhichjis fastened toltheinner' side of the lay".

For this pur-" pose, let usrefertoliligures;6;] and 8.; r In Figure 6the shuttle is at therighthand;side ofthe warp andlthe'needle 53iis fabrlc.

. left hand side of the loom passes the shuttle through the new shed tothe position shown 'inFigure .8. The loop which is in the shuttle mustnow be released and a new loop from the needle placed thereon, as shownin Fig ure 6. Y

. It is apparent from an inspection of the figures above mentioned thata double warp strand is woven into every pick of the To accomplish theresult above, described, let us assume that the lay27 is in the positionshown in Figure 2. The crank 129 moves about the shaft 131 inthedirection shown by the arrow and by reason of the gears 132 on saidshaft and the gear 133 on the shaft 57 the shafts will rotate oppositedirections.

In the position of the lay, as shown in Figure 2, the shuttle 87 is justabout to be thrown from the right hand side of the loom through the warpshed and by the time the shuttle reaches the receiver on the left handside of the lay, the crank 129 will have made a little more thanone-half of arevolution but the gears 132 and 133 are so arranged thatthe speed of the shaft 57 is exactly onehalf the 7 speed of the shaft131.

Consequently, the cam58 will during same period move slightly more thana quarter of a revolution and the cam .1s so timed that at the veryinstant the shuttle reaches the receiver 39, the said cam will disengagethe ogee crank arm 62 and the tension thus being released, the springs73 will move the disc 49 firmly against the disc 51 and thereby clamp thethread X. v, d

The amount of thread which has beencarried bythe shuttle in its movementfrom the right tothe left hand side of the loom will be exactlythatrequired to complete its return to the receiver 38 on the right hand si de of the loom and to draw the same firmly into the selvage whichis'being formed on the left hand side of the fabric. i V V. V

' In order tocomplete this return of the shut-;

tle, the lay 27 is moved forward on the swords 31 and on the returnstroke and at about the position of the crank shown in Figure 2, thepicker stick on the left hand side of thejloom will operate and pass theshuttle back into the receiver 38. At the end of'this stroke the laywill be in about the same position as. shown in Figure 2, but the crank129 will bea' little more than 180 from the position shown in thatfigure and the cam 58 on the shaft 57 will be slightly more than 'tionshown;

.j t m the si- As the lay continuesto move'forward the operation of thecrankl29, the cam 57 will engage the, follower 74, pulling the for; wardend of the same downward so that the rod 79 ;will bring theactuatin'gpin83 down.

onto the top ofthe inner end of the lever in the shuttle 87. This willcompress the spring 98 and raise the pin 96.

At this movement, the selvage heddle 118 is raised and the loop vwhichis designated ward position,the needle 53will have entered the channel92 in the shuttle 87 and at the right of the pin 96 That part ofthethread which I have designated 137 in Figure 6 will be drawninto theundercut slot 94 so that the thread will be disposed behind the slightdepression 97 into. which the pin extends when the same is lowered,

While in this position the cam 58 ceases to hold the rod 79 down and thespring 77 on the rear of the cam follower 74 will force the rod upwardand thereby disengage the actuating pin 83 from the end of the lever 89.The lay then moves to the rear and as it does so, it operates the bellcrank 111 through the link 112 and the serrated arm 117 of the bellcrank will pull the loop from the hook 126 andlahrush the same over ontothe woven fabric As the loom returns to the position shown in Figure 2,the cam' 58 will have'entirely disengaged the follower 74 and willengage the upper arm 62 of the ogee crank 59 and through the wire 64will pull the shaft 68 carrying the disc 49 outward, thereby releasingthe tension on the weft thread X, so that when the picker stick strikesthe shuttle, the weft thread may be paid out as required.
